PersistentMemoryConfig

public PersistentMemoryConfig()

PersistentMemoryConfig

public PersistentMemoryConfig(@Nonnull
                              PersistentMemoryConfig persistentMemoryConfig)

Constructs an instance with copying the fields of the provided PersistentMemoryConfig.

Parameters:

persistentMemoryConfig - The configuration to copy

Throws:

NullPointerException - if persistentMemoryConfig is null

Method Detail

getDirectoryConfigs

@Nonnull
public List<PersistentMemoryDirectoryConfig> getDirectoryConfigs()

Returns the persistent memory directory configurations to be used to store memory structures allocated by native memory manager.

By default there are no configuration is set indicating that volatile RAM is being used.

Returns:

the list of the persistent memory directory configurations

setDirectoryConfigs

public PersistentMemoryConfig setDirectoryConfigs(@Nonnull
                                                  List<PersistentMemoryDirectoryConfig> directoryConfigs)

Sets the persistent memory directory configuration to the set of directories provided in the directoryConfigs argument.

If the specified directories are not unique either in the directories themselves or in the NUMA nodes specified for them, InvalidConfigurationException is thrown. Setting the NUMA node on the subset of the configured directories while leaving not set on others also results in InvalidConfigurationException.

Parameters:

directoryConfigs - The persistent memory directories to set

Returns:

this PersistentMemoryConfig instance

Throws:

InvalidConfigurationException - If the configured directories violate consistency or uniqueness checks.

NullPointerException - if directoryConfigs is null

addDirectoryConfig

public PersistentMemoryConfig addDirectoryConfig(@Nonnull
                                                 PersistentMemoryDirectoryConfig directoryConfig)

Adds the persistent memory directory configuration to be used to store memory structures allocated by native memory manager.

If the specified directories are not unique either in the directories themselves or in the NUMA nodes specified for them, InvalidConfigurationException is thrown. Setting the NUMA node on the subset of the configured directories while leaving not set on others also results in InvalidConfigurationException.

Parameters:

directoryConfig - the persistent memory directory configuration

Returns:

this PersistentMemoryConfig instance

Throws:

InvalidConfigurationException - If the configured directories violate consistency or uniqueness checks.

NullPointerException - if directoryConfigs is null
